1.2 U value of a window Please calculate the difference in % of WINDOW U-value for a large and a small window of two scenarios presented below. Explain the reason(s) for the difference between the final values (one sentence). Scenario A: one larger window Scenario B: two smaller windows W =0.1 m W H=1.2 m W =0.1m =0.1 m H=1.2 m L=1.8 m L=0.9 m L=0.9 m Uglazing = 0.7 w/m2k Uframe = 1.4 W/m2K I spacer = 0.1 W/mk
